Prop Question

[Striper Blues]

I'm considering installing a stainless steel prop on my 1989 Grady White sailfish with a 460 ford/king cobra setup.<br /><br />I checked with GW and they told me it takes a 15X17 which is what it has now only in aluminum.<br /><br />What are the pros/cons of changing to a 15X17 stainless prop?<br /><br />Thanks,<br />Pat

Re: Prop Question

aluminum is much cheaper to repair if you ever have any problems. Plus it can "give a little" if you hit something with it. Therefore possibly spareing damage to something else. They can corrode.<br /><br />Stainless ones don't give, thier blades are usually a little thinner, giving better efficency, but they are expensive to buy and repair.<br /><br />Personally I don't have a race boat, and I like my aluminum just fine. I can buy 3-4 props new for what it costs for a stainless one. And if it gets nicked up a little It can be fixed cheap, about 30 bucks for a weld,grind,balance add 40 bucks for a hub if needed. But I have a Mercruiser, and have a good prop shop close to me. I would think an OMC would be compareable.

Re: Prop Question

I agree with the Kid for the most part. Most Stainless steel props are doubled cupped and get a little better bite. Also thiner so turn a little eaiser. Same pitch / diameter and same number of blades and it might get you 1/2 Mile per hour Increase in speed. Only real difference is they do not nick as easy but if you hit something hard blades do not just fold over either so more chance of gear box or shaft damage. Hub should slip but if it does not something must give.<br /><br />Personaly I like the stainless but I do not run where I will hit anything solid. Still a floating stick or log could be hit and cause damage.
